Abstract
Ti or a high-Ti alloy is melted in a container composed of high-purity CaO materials on its inner sides. The materials are composed of not less than 99% by weight of CaO, not more than 0.1% by weight of SiO.sub.2, not more than 0.02% by weight of Fe.sub.2 O.sub.3, and not more than 0.5% by weight in total of other metal oxides under a non-oxidizing atmosphere. CaO refractories for use in the melting of Ti or a high-Ti alloy contains not less than 99% by weight of CaO, not more than 0.1% by weight of SiO.sub.2, 0.02% by weight of Fe.sub.2 O.sub.3, and not more than 0.5% by weight of other metal oxides.
